Scleroma, caused by Klebsiella pneumoniae, is a rare chronic disease affecting the upper respiratory tract, with unclear causes and numerous immune system disturbances.
A study analyzed the local immunity in the oropharynx of 92 scleroma patients and 20 healthy individuals, measuring several immune factors in their oropharyngeal secretions.
The results showed significant decreases in secretory and monomeric immunoglobulins in scleroma patients, indicating a deficiency in local immunity that may contribute to the chronic inflammation seen in the disease, suggesting a need for immune therapy in treatment.
